Description

Based on the same rules as the hit KenKen(tm) game, as printed in the New York Times and The Times (uk).

Related to Sudoko, but with a mathematical twist - use the arithmetic challenges in each cage to help solve the puzzle.

My favorite time waster I have played this game constantly since I found it soon after its release. The developer made some significant UI changes but then was receptive to our requests to make the old interface available as an option. It's now back to its position at the top of my favorites list.

I think this is the best thing I've downloaded, ever. It never gets old, because there are infinite puzzles (as far as I know? I've played at least 800 since I got the app about 18 months ago). Don't think the difficulty ratings scale perfectly, but that does mean the game makes you keep learning.

Don't download the update! I'm so bummed, this was my favorite game and the app was awesome! Unfortunately, I just downloaded the updated version and not only can I not change the screen orientation, but I can't play at all--the number pad isn't there. Super sad, I shouldn't have tried to update. I even uninstalled and reinstalled as someone recommended with no luck.

One of the Best Ken Ken Apps I play all the time on this app. Puzzles range from 4 x 4 to 9 x 9. There are an unlimited number of puzzles that can be created. One problem is that all puzzles required all four math operations. Other apps have the option of choosing which operations to use, but those apps cost more.

Used to love this game The new swipe interface is absolutely dreadful. I used to play dozens of times a day and now am uninstalling. Too bad you ruined the only game I had installed on my phone

Well Done! Well thought out with all the game-in-progress options that one could ask for. Thanks for this little gem! [Added] The latest v2.12 update fixed the Back key FC problem. Thanks!

v2.12 has just been released to address the force close issue.

Love the game but new input is impossible I've loved this app since I first found it, but the new input method is not at all user friendly, especially on larger size puzzles with squares right on the edge of the screen. Original app would be a 5/5 for me, but only a 3/5 now because it's simply too hard to use. If the new input is reverted or at least made optional I'll give 5/5 again

Ben Buxton November 23, 2013

The new input method can be disabled in the settings.

Adrian Spencer November 27, 2013

Doesn't work any more Can play 1 game after install but after that pressing new game does nothing. Was fine b4 the update earlier in November. Please revert!

Leah Sharp January 5, 2014

Too many extra features In general, it is a great game and good app. But I wish I could turn off the punishments for using hints and the statistics. Also, the color options could be improved.

Joe Marchese July 24, 2014

I like the updates. The statistics for cheating are good. I don't care for the statistics tied to 'maybes'. It's annoying because I get to play in short bursts and it keeps my place in complex puzzles.

Luke Reilly October 9, 2016

Wonderful game Totally addicted. App performs well, no crashes yet! I like that it automatically saves when I close out of the app and resumes when I come back to it. Thanks!

Annoying Mode switches from Normal to Maybe randomly. Cannot reset error message.

Nudnik Im December 17, 2016

:( no game statistics since update I love the app. In fact, I'm giving it 5 stars despite the game statistics now a black screen (with what may be the stats bunched up on a tiny cube in top left corner). Can you put a link to previous version? There was really nothing wrong with that one...

Myrddin Emrys April 3, 2015

Free and Excellent I enjoy the dynamics between the differing totals and results possible at the differing sizes and skill levels. Just going up a size category changes the game as you have to incorporate another number into your mental factorization. It has been my go-to casual game for over a year.

Adam Agueci February 10, 2016

How do I play archived games? I had this app on an old phone and I used to be able to play archived games (I'd try beating puzzles in previously gave up on). How do I do that in this version? Thanks

Bill Ebob September 27, 2015

fantastic! can't get enough of it - very customizable. get it! so far I've spent 2170 hours playing the 7x7 level and still love it!

A Google User October 4, 2014

Loving the new interface Was already great, now even better

Sarah Carlton June 29, 2015

I have loved and played this game for a long time! This is a great game. I wish they would bring back the option to save boards though.

Mick P May 26, 2014

Great Game The interface is great. If you don't like swipe then you can change it in the settings (I like the using the buttons so I turn it off). This is by far the best mathdoku game out there.

A Google User March 12, 2014

New update sucks Was great until this update. Keypad doesnt appear on my samsung galaxy pop... Pl bring d old version back...

Lisa Annisa April 20, 2017

Simple and fun. Can create various puzzle size and difficulty. Great time waster.

saicharan mahendrakar January 15, 2015

Satisfies my nerdgasm Such a good game for free without ads is really appreciated. I'll definitely recommend this game.

Anup Raj Aryal February 12, 2014

Game problems Why n how useless number gets entered automatically in the cells.

A Google User September 17, 2014

Lame No puzzles give even one number to help get started. All puzzles are trial and error instead of pure logic.

A Google User February 7, 2014

good game! yellow number in maybe mode not clear, prefer larger black.

Mr Hbrthwt718 June 17, 2014

Awesome game Challenges me daily

Bob Tuckwell July 11, 2014

What happened Was perfect until the last update now uninstalling and looking elsewhere.

Swapnil Srivastava November 26, 2014

Basic was better! Make the board as large as possible on the screen - buttons don't need to be that big!

Armando Cendejas February 24, 2014

Great Puzzle App The app works great and it's a fun, challenging game. It used to be 'buggy' when they did some updates, but it works great now.

Raymond Canady May 28, 2014

Great game Great way to kill some time and give your brain a workout.

Marie de Blois May 13, 2015

Great quick game app Requires no special privs, loads quickly, takes some brain power. Recommend.

Ori Ziv April 28, 2014

Would love some bigger grid sizes. 12x12 or 15x15?

Shai Azoulai December 3, 2016

Best Ken Ken game on any platform!

Adnan Akpinar May 31, 2016

Best Doesn't want too many permission, simple, lightweight and best. Thank you.

CynCity Kitty December 30, 2014

Ok app!

A Google User July 3, 2014

Love the new features This is the best free Kenken/Mathdoku app out there.

Ryan L October 14, 2015

Exactly what you want Without a bunch of permissions it doesn't need. This is how you do a game.
